Roco 6200063 3-piece set: Rack-and-pinion railway passenger train, Sonnblick-Bahn
Wagon set with two passenger coaches and a baggage car of the Sonnblick-Bahn. With their unique combination of mountain landscape and bold routing featuring numerous bridges and tunnels, rack-and-pinion railways are particularly fascinating.The movement of the train is achieved through the engagement of a toothed wheel in a toothed rack positioned in the centre of the track, as the usual friction generated between wheels and rails is insufficient for the steep inclines.In rack-and-pinion railway of the so-called mixed system, where friction sections alternate with toothed rack sections depending on the gradient ratios, the tractive force is exerted by one and the same machine. A particularly large number of private rack-and-pinion railways are found in the Alps, and these attract tourists from all over the world.
